This oven is great. I replaced an oven that was installed with the house in the 60’s. It preheats quickly, the fan can be loud like some of the reviews said, but it doesn’t stay on constantly while cooking so it hasn’t bothered me. It has cooked evenly and has come pretty close to all of the cooking times for recipes. My 2nd time using the oven was to cook a Thanksgiving meal (all of the sides). I was very pleased.
